GUSTAV NOWAK, OF BISTRIT Z, AUSTRIA-HUNGARY.

SPECIFIGATION forming part of Letters Patent No. 636,835, dated November 14, 1899.

Application filed July 12, 1899. Serial No. 723,581. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAV NOWAK, a subject of the Emperor of Austriallungary, residing at Bist-ritz, in the Empire of Austria- Hungary, have invented certain new and useful Improvements in Apparatus for Generating Acetylene Gas, (for which I have applied for patents in Germany, dated June 12,1899, and in Hungary, dated January 30, 1899,) of which the following is a specification.

The present invention relates to an apparatus for generating acetylene gas which obviates all injurious consequences of the development of gas after the carbid has been removed from the water. The apparatus hitherto made all possess the disadvantage that this subsequent development of the moist,

carbid has not been taken sufficiently into consideration, as only the removal of the carbid when a certain pressure was attained was taken into account. This subsequent development can, however,attain great dimensions and where space is scarce give rise to explosions, for which reason the surroundings where such apparatus are used are subjected to great danger. In the present invention this subsequent development is taken into special consideration, space for the acetylene thus developed being formed.

In the drawings representing one form of this invention, Figure 1 shows a vertical section of the entire arrangement, and Fig. 2 a horizontal section on line 2 2 of Fig. 1.

The apparatus consists of a generator A and gasometer B, which are connected together by tubes 0 0 One of these tubesviz. c-passes through the bottoms of a vessel 0. and water-tank a and is provided with two valves 0 and 0 The second tube 0 passes from the side of the float a in the watertank upward and is connected by means of a rubber or other similar tube 1) to the tube 0 which opens out into the tube 0 which latter opens out into a gasometer b. The generator A consists of a water-tank a, in which two guiding-rails s are arranged diametrically opposite each other. In the watertank a float a is arranged, which is provided with four guiding-rollers to bear on the rails s and with an air-tight cover f. The upper edge of the float has a flange provided with two notches f Through these notches f the ends of a bow f pass below the flange, after which the bow can be turned on a vertical axis. By this means the coverfcan be pressed upon the flange with the agency ofa screw and hand-wheel m, and the float is thus hermetically closed.

On the support 70, formed near the upper edge of the float by an angle-iron, the carbid vessel a is suspended, the bottom of which is preferably provided with a number of perpendicular conical tubes a Through the middle of the bottom the tube 0, leading to the gasometer, is passed. This tube can be closed by the cock 0 and carries a toothed segment r, rotatably connected to a second cock, which is in engagement with a toothed rack r, secured to the gasometer.

The operation of the apparatus is as follows: The float or bell a of the generator is raised and secured until the vessel a has been filled with the necessary carbid, which should be distributed as evenly as possible on the bottom. The cover, which has been removed for the purpose of filling the vessel, is again put on and screwed tight, after which the float or bell is slowly lowered into the water. Air can escape through a cock arranged at a suitable point of the generator. When the air has been displaced by the acetylene gas generated, the air-cock is closed and the cock 0 of the tube 0 opened. At the lower position of the gasometer the valve 0 is opened.

The relative weights of the two bells are so chosen that the bell a of the generator is only raised when the bell b of the gasometer has been raised. When the bell b rises, the rack 11 comes into engagement with the toothed segment after a certain time, depending upon the construction of the apparatus, and thus gradually closes the valve 0 When the valve 0 is quite closed, the gas further generated raises the bell at until the vessel 0. has been raised above the water. The moist carbid will continue to generate acetylene for some time, which gas will,when the generatorbell has risen high enough, pass through the opening 10, tube rubber or like tube '0, tubes 0 and 0 into the gasometer-bell b.

When the acetylene is to be used, the cook 00 of the tube d is opened. The bell b of the gasometer descends gradually and by doing so opens the valve 0 whereupon the gas in the bell a is utilized. After both bells have descended and the water again comes into contact with the cal-bid the operation commences again. Several generators can be connected to the same gasometer and should preferably come alternatingly into action, so that a continuous cleansing and filling may be effected.

\Vhat I claim, and desire to secure by Letters Patent of the United States, is

1. The combination of a gasometer, a watertank beside the same, a vertically-movable cylinder in said tank, a carbid-containing receptacle in said cylinder, means for closing the upper end of said cylinder, and apipe leading into said cylinder and through the bottom of the carbid-holder, said pipe communicating with the gasometer; with a pipe connected to the said cylinder below the bottom of the carbid-holder therein, and a flexible connection between said pipe and a pipe communicating with the gasometer.

2. The combination of a gasometer, a watertank beside the same, a vertically-movable cylinder in said tank, a carbid-containing receptacle in said cylinder, means for closing the upper end of said cylinder, a pipe leading into said cylinder through the bottom of the carbid-holder, said pipe communicating directly with the gasometer, a cut-0E valve in said pipe, and a regulating-valve in said pipe controlled by the rise and fall of the gasometer; with a pipe connected to the said cylinder below the bottom of the carbid-holder therein, and a flexible connection between said pipe and a pipe communicating with the gasometer.

3. The combination of a tank, the gasometer thereon, a second tank, a vertically-movable cylinder therein having a removable upper end or head, and means for closing said head, a carbid-holder suspended from said cylinder having a series of conical tubes in its bottom, a pipe communicating with said carbid-holder and the gasometer, said pipe being provided with a cut-off valve and a regulating-valve, the regulating-valve being provided with a segment engaging a rack on the gasometer.

4. The combination of a tank, the gasometer thereon, a second tank, a vertically-movable cylinder therein having a removable upper end or head, and means for closing said head, a carbid-holder suspended from said cylinder, a pipe extending through said carbid-holder to the outside of the cylinder and tank containing the holder and communicating with the pipe leading into the gasometer; a cut-off valve and a regulating-valve in said pipe, the regulating valve being provided with a segment engaging a rack on the gasometer, a second pipe communicating with said cylinder below the bottom of the carbid-holder and flexible connections between said pipe and the pipe leading to the gasometer, all substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.

GUSTAV NOWAK.
